Abstract

Plasmonic properties of metallic nanoparticles depends on how accurate the initial plasmon modes in interaction of the nanoparticle surfaces. Changes in the optical properties of spherical nanoparticles that are associated with symmetry, alters the interaction is plasmonic modes, which in turn leads to the creation of plasmons with new features. We used the Lorentz-Mie-based theory to simulate the optical properties of silver nanoparticles and gold-silver core-shell nanospheres. The results showed that by increasing the shell thickness of silver, plasmon resonance peaks are shifted to shorter wavelengths, while the peak is get higher. Also, increasing the radius of silver nanoparticles for individual waves that plasmonic resonances occurred in them, are moving toward longer wavelengths.
